2x2 matrices of determinant 1 with integral entries
Hatice Boylan
İstanbul University, Turkey
Özet : Already the group SL_2(Z) of 2x2 matrices with integral entries and determinant 1 provides beautiful and interesting mathematics and still deep open problems. We shall give an overview over various aspects of this group, indicate its connections to geometry and number theory, and shall finally arrive at the theory of its finite dimensional representations. In the third part of my talk I shall discuss extensions of the theory to Hilbert modular groups, i.e. groups of 2x2 matrices and determinant 1 with entries in the ring of integers of a given number field. In particular I shall describe a few results of my own work in this domain.
